Kesha performs “It Ain’t Me Babe” at the Billboard Music Awards on May 22, 2016, in Las Vegas.

Kesha has dismissed a California lawsuit alleging hit-making producer Dr. Luke sexually and emotionally abused her, but a similar case will remain in play in New York.

Monday's dismissal of a Los Angeles case comes amid an effort by the singer to get new singles and an album released despite her high-profile fight with her former mentor.

Her attorney, Daniel Petrocelli, said the dismissal was filed so she can focus her legal efforts in New York, where she has also sued the producer alleging he frequently ridiculed her for nearly a decade and at one point drugged and raped her.

Dr. Luke, whose real name is Lukasz Gottwald, has denied Kesha's allegations and accused her of suing to try to obtain a better recording deal.

Petrocelli said Kesha has delivered 28 new songs to Dr. Luke's record label and Sony Music Entertainment and hopes new singles and albums will be released soon. "We have conveyed to Sony and the label Kesha's strong desire to release her next album and single as soon as possible," Petrocelli wrote in a statement.

Kesha is appealing two rulings in New York that prevented her from breaking her contract with Dr. Luke's label, and that dismissed her claims of sexual and emotional abuse. The April ruling by Manhattan state Supreme Court Justice Shirley Werner Kornreich stated that Kesha's rape and abuse allegations couldn't move forward because the alleged incidents happened outside New York and fell outside the statute of limitations.

"If Kesha is voluntarily dismissing her claims in the California case, it is because she has no chance of winning them," Dr. Luke's attorney, Christine Lepera, wrote in a statement. "Kesha never should have brought her false and meritless claims against Dr. Luke in any court."

Kesha's career has been in limbo since she first sued Dr. Luke in October 2014, alleging his abuse caused her to develop a severe eating disorder that required her to enter rehab.

In May she delivered a standout performance of Bob Dylan's "It Ain't Me, Babe" at the Billboard Music Awards, but was only permitted to do so after Dr. Luke's label withdrew objections to her appearance because they feared she would use it as a platform to attack the producer.

Dr. Luke has never been charged with any crime and has vehemently denied he abused the singer. His lawyers note that during sworn questioning in another lawsuit in 2011, Kesha said Dr. Luke "never made sexual advances" toward her or gave her the date-rape drug known as a "roofie."
